BELT BUCKLE.

Original application led .Tanuary 31, 1921, Serial No. 441,232. Divided and this application filed August To all whom t may concern.'

Bezit known that I, SAMUEL BUCHSBAUM, a citizen of the United States, residing at Chicago, in the county of Cook and State of a Illinois, have invented a certain new and useful Improvement in Belt Buckles, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to belt buckles and more particularly to a belt buckle provided with a knuckle joint clamping lever and is a division of application Serial Number 441,232, filed January 31, 1921.

It is the purpose of the invention to provide a belt buckle `with clamping means comprising a belt clamping element having upturned end portions to prevent marring of :o the belt thereby that is slidably and tiltably mounted in the front plate of the buckle and which Vis adapted to be moved into engagement with the belt by means of a clamping lever having an angular end portion adapted to engage the concave face of said clamping element.

It is a further purpose of the invention to so construct a belt buckle that very little power need be applied to the clamping lever in order to clamp the belt end therein, and in which the belt will readily slide when the clamping lever is released.

It is a still further object of the invention to provide a belt buckle with. a clamping means wherein the clamping lever does not contact with the belt and consequently no marring of the belt will occur.

It is another object of the invention to provide a belt buckle having a clamping 1.1 plate that is connected with the front platev of the buckle by a pin and slot connection to provide for movement of said clamping plate toward and away from said fronty plate by means of an angular clamping lever. Other objects and advantages of the invention will appear as the description of the accompanying drawings showing certain forms that my invention may take, proceeds. However, I desire to have it distinctly understood that I do not intend to limit myself to the exact details of structure shown in the drawings and described in the specification, but intend to include as part of my invention, all such obvious changes and modifications of structure as would occur to a Serial No. 489,857.

person' skilled in this art and as would fall within the scope of the claims.

In the drawings:

Fig. 1 is a front elevation of the improved belt buckle showing the same applied to a belt, the belt being partly broken away;

Fig. 2 is an edge view thereof, looking at the side edge of the belt;

Fig. 3 is a longitudinal sectional view of the buckle taken on line 3 3 of Fig. 1;

Fig. 4 is a fragmentary longitudinal sectional view of a modified form of buckle;

Fig. 5 is a perspective view of a further modified form of clamping element; and

Fig. 6 is a view similar to Fig. 3 of a belt buckle rhaving a single pin and slot connection on each side thereof.

Referringrin detail to the drawings., thek improved belt buckle comprises a front plate 6 curved longitudinally as shownl in Figs. 2 and 3 and provided with rearwardly extending side flanges 7 that are provided with suitable openings 8 for the pivot pin 9 which is carried bythe clamping lever 10 which may be formedras shown in Fig. 3 so as to provide an eye at 11 to receive the pin 9 and having an elongated eye at the end portion thereof at 12 to receive the loop 13 on the belt extremity 14.

It will be seen from Fig. 3 that the clamping lever comprises a long arm and a short arm extending at substantially right anglesy to each other. The short arm 15 is adapted to engage a belt clamping' member 16 which is curved as shown in Figs. 2 and 3 so as to turn the end edges thereof away from the front plate and the belt, and which is provided with end portions or lugs 17 that are adapted to operate, in slots 18 provided in the flanges 7.

The lugs 17 do not fit snugly in the slots and have a loose sliding movement therein so that the clamping member 16 will slide toward the front plate 6 andwill `also rock Vslightly. relative thereto when the clamping lever 10 is moved in a clockwise direction into the clamping position shown in Fig. 3.

The member 15 moving along the concave face of the clamping plate 16 will draw the same by a combined sliding and rocking movement into clamping position relative to the free belt extremity 19. By this arrangement, the clamping lever does not contact with the belt extremity and thus any scraping or biting action thereof which wouldinplate 16 will be released and will move away 'o from the plate so as to loosely contact with with the same and permit withdrawal of the =f belt end 19 from between the clamping plate and the front plate.

The clamping plate may be provided with serrations or grooves or roughened port-ions 2U as is shown tor the clamping member 16 in lig. #i the member 16 being mounted in the front plate 6 in slots 18 provided in the side Aflanges 7 in a similar manner to the mounting of' the plates 16 in Fig. 3.

The clamping leverV 1G in this form is shown as having an inteoral pivot member 9 and is provided at the extremity thereof with a gripping member 21 pivoted to ears 22 and having teethQS that are adapted to grip the belt extremity lfi, it being, ot course. understood that the tree belt extremity 19 is gripped between the front plate 6 and the clamping member 16 in a manner similar to that of the belt extremity 19. Instead otl providing grooves or serrations to provide gripping means on the'clamping plate, the holes or openings 24; may be provided as shown in F ig. 5 in the clamping plate 16. Y

In Fig. 6 is shown a belt buckle having a front plate 26 curved longitudinally, and provided with rearwardly extending side flanges 27 between which is pivoted the clamping lever 28 which ,comprises a long arm and a short arm as previously described. The long arm is provided with ears 29, carrying the belt gripping means 8O engaging the belt extremity 31. The short arm ot the clamping lever is adapted to engage a belt clamping member 32 which is shaped as shown in Fig. 6 so as to have the ends thereof extending rearwardly away trom the belt so as to avoid any sharp edge engaging the belt. The member 32 is provided with means engaging guide slot` 33 in each of the ears 2T in a similar manner as shown in Figs. 1 to 5 except that a single guideslot is used on eac-h side. As the lever 28 is swung clockwise the short end the-re-A of is adapted to move the beltclamping member 32 toward the front plate 26 and clamp the belt extremity 34 between the said belt clamping member and front plate.

From the above it will be seen that a belt buckle has been provided that will grip the plate having rear ends toward the middle thereo'moimtcdbe- 'I tween said sidev flanges, and being connected to said flanges with a pin and slotconnection at. each end t-hereot to provide for movement y thereof toward and away from said front plate, and means for moving said clamping plate toward said front plate, said clamping plateI being mounted on said front plate inn depcndently of said last mentioned means.

2. A belt buclrle ot thecharacter described comprising a curved sheet metal front )late having side flanges, a curved'sheet metal clamping plate positionedl between? the side flanges ot said front plate, said clamping, plate being of sharper curvature than said iront plate rand having its convex side toward saidV front plate and being mounted tor movement toward 'andv away from said front plate by means of a pin and slot connection, and means for moving said clamping plate toward said frontA plate comprising an angular clamping lever enea ino said clam in late on the con-y cave side thereof at one end thereof and ing provided with belt gripping means at` the other end thereof.

3. A belt buckle of the character described comprising a front plate having rearwardly extei'iding side flanges, having guide slots thereon, a clamping plate having` a curved belt engaging portion and provided with lugs operating in said slots whereby7 said clamping plate is movable toward and away from said fro-nt plate,'said belt engaging portion having its convex side facing said front plate and adaptedY to engage said belt, and means for moving said clamping' plate toward said front plate comprising a' clamping lever pivotally mounted between said side llanges and engaging said clamping plate. i Y

In witness whereof I hereunto subscribe my name this 29th day of July A. D.'1921.

SAMUEL BUCHSBAUM.
